Let's talk about a couple of problems with the process, just for future reference. It can be very stressful on deciduous trees to be dig out of the woods, and particularly so while they still have all of the leaves on. If you are going to take a tree in that manner, best to wait until it is fully dormant. Next, fertilization is one of the very worst things you could have done, especially with a fast acting soluble product such as MiracleGro. A newly transplanted woody plant shouldn't be fertilized at all, or with a very small amount of a very slow release product.

Not knowing anything about your digging/handling/planting process, I can't help but worry about this tree. I am not meaning to be critical, but you should know that it is very easy to kill a perfectly fine tree.....when you don't know what you are doing. For example, a tree that has spent it's life in the woods might find it very difficult to survive in the middle of a lawn.

The good news is that what you are seeing now is the death of all of those leaves as a result of the digging. It doesn't necessary mean that the whole tree is dead. New leaves will not re-grow this season. That's not good for the plant, since the leaves drive the process in which all plants make new roots! But, plants can be resilient and crape myrtles are tough. I'd water (only when the soil begins to dry somewhat...if you keep the area soggy this tree is REALLY a goner.) periodically throughout the winter, put away the fertilizer, and wait for spring. MULCH! You can test for branch die-back in a couple of months or so, but I wouldn't bother with that. Parts of this tree are sure to die, and the best way to find out what you will have left is to see what (if anything) comes back in the late spring. Remember, crape myrtles can be the last to break bud in the spring.

Something to think about. If this tree was a wild volunteer, then it is seedling stock and not one of the disease and insect resistant cultivars. That can mean, since there is no way to know the genetic history of this tree, that it will be prone to powdery mildew and aphids, especially after this extreme stress it's been through. A wiser (and happier for ALL) decision would have been to purchase a small named hybrid in the color and future size of your choosing and watch it grow by leaps and bounds! The small 2.5 foot crape purchased by us earlier this year is now 5 feet tall and will reach 8 feet easily next year. It was in a 3 gallon container!

Removing crapes from wild areas is a GOOD thing, as they are almost becoming a pest species in warmer climates such as yours....but probably not the best way to bring in a quality tree to your landscape.

Good luck! And if you think about it next summer, let us know how your tree did.
